Fentanyl-stimulant polysubstance use is a major driver of America’s overdoses crisis, contributing to widening racial disparities in overdose outcomes and disproportionately impacting homeless populations. Relationships between fentanyl-stimulant polysubstance use, drug-related harms, and health disparities among people experiencing homelessness are poorly understood. This prospective, longitudinal qualitative study will characterize fentanyl-stimulant polysubstance use (cocaine, crack cocaine, methamphetamine) in a racially and gender diverse sample of people experiencing homelessness across two US cities (New York, NY; San Francisco, CA), and collaborate with stakeholders to co-develop evidence-informed, nationally-scalable research, policy, and program recommendations.
